IT executives understand the value of cloud services and videoconferencing tools, but one of the chief concerns remains the strain those services put on network bandwidth, according to a study released today.

Network performance monitoring firm Network Instruments said there is a "management storm" brewing as executives attempt to meet bandwidth demands and keep tabs on the performance of new technologies as they are embraced by the enterprise.

Some 60% of organizations surveyed have adopted cloud computing and they expect on average that about one-third of their apps will run in the cloud within 12 months. Compared to last year, there has been a 10% increase in users of SaaS, IaaS and private cloud. Even as the cloud is being adopted, executives have concerns, most notably about corporate data security and a lack of end user monitoring of cloud services, as well as the impact on bandwidth needs.

"While IT teams embrace cloud services and video conferencing as a way to increase cost savings and business flexibility, these technologies introduce new components and environments which make ensuring positive end-user experience all the more challenging," said Brad Reinboldt, senior product manager of Network Instruments, in a statement.

The survey found that 55% of respondents have implemented a videoconferencing system, with an estimated 70% adoption rate expected within a year. Of enterprises that have deployed videoconferencing, more than three-quarters use the technology in conference rooms, while 60% have videoconferencing on PCs.

Allocating bandwidth to manage video traffic is a concern: One-quarter of executives predict that video could consume half of network traffic within a year. Training, user knowledge and a lack of tools to monitor performance were other top concerns cited.

The study included responses from 163 IT executives in North America, Europe and Asia Pacific.
